I got an interesting article today about how plants talk to us and tell us what they are lacking. here’s the link:
http://www.lahuertinadetoni.es/como-abonar-y-falta-de-nutrientes-en-las-plantas/ It is in Spanish but you can see the web page translated to English.
We will look more closely at how we can provide these nutrients by lack:
– Lack of Calcium: To add calcium, we can use the eggshells .
– Lack of Potassium: We can apply irrigation with banana you , we can irrigate with Russian comfrey purin !.
Pay And as plant nutrients missing and one will never be a problem. One last recommendation and very important, is just as bad about nurturing a plant, that lacks nutrients, so do not abuse of fertilizers.
